TDA19978AHV Quad HDMI 1.4a receiver interface with equalizer (HDTV up to 1080p, up to UXGA for PC formats)

The TDA19978A is a four input HDMI 1.4a compliant receiver with embedded EDID memory. The built in auto-adaptive equalizer improves signal quality and allows the use of cable lengths up to 25 m (laboratory tested with a 0.5 mm (24 AWG) cable at 2.05 gigasamples per second). The HDCP key set is stored in non-volatile One Time Programmable (OTP) memory for maximum security. In addition, the TDA19978A is delivered with software drivers to ease configuration and use.

The TDA19978A supports:

The TDA19978A includes:

The TDA19978A converts HDMI streams with or without HDCP into RGB or YCbCr digital signals. The YCbCr digital output signal can be 4:4:4 or 4:2:2 semi-planar format based on the ITU-R BT.601 standard or 4:2:2 based on the ITU-R BT.656 format. The device can adjust the output timing of the video port by altering the values for tsu(Q) and th(Q). In addition, all settings are controllable using the I²C-bus
